Authorities said Samantha Schermanhorn and Kaylie George, both 13, had to be flown by helicopter to a hospital after they fell asleep while tanning in the road and were hit by the vehicle.

"I jumped off the tractor, ran across the road, ran to the road," neighbor Keith Gilbert said. "I didn't get his attention in time, and he hit both girls."

Nicole and Nicholas Beck, who are Schermanhorn's cousins, said their 19-year-old brother was driving and had stopped at a stop sign before making a turn and hitting the two girls.

"They told us they fell asleep on the road, and my brother turned and hit them," Nicholas Beck said.

The Becks said 911 was called, and the victims were conscious when ambulances arrived to take them to a nearby site to meet the helicopters. They said their brother was questioned after the crash, but it was just an accident.

"I was crying real bad and shaking," Nicole Beck said.

Both girls were listed in fair condition with lacerations to their ears, scalp and a few other areas.
